How do I make sure redacted text is truly gone from my PDF?

Use the Redact tool, not just a black rectangle. After applying redaction, run the 'Sanitize' tool to remove hidden data. Save the document. Then, try to select and copy the area where the text was. Paste it into a new document. If nothing appears, the redaction worked.

Redacting with the proper tool permanently removes the text or image data from the PDF file. This means the information is truly gone and cannot be recovered. Drawing a black box only covers the text visually; the text data remains underneath and can be easily copied and pasted, making the information still accessible to others. Always use the 'Redact' tool for security.

Redacting only removes visible text and images. However, PDFs can contain hidden data like metadata (author, creation date), layers, or revision history. This hidden data might still contain sensitive information. Sanitizing the PDF after redaction removes all this hidden data, ensuring that no sensitive details are accidentally left behind, making your document fully secure.

For large documents with many instances of specific patterns like SSNs or account numbers, use Acrobat's pattern-based auto-redaction feature. This allows the tool to find and mark all occurrences automatically. After auto-redaction, it's a good practice to have a second person (peer-QC) review a random sample of the redacted areas to ensure accuracy and that no SSNs were missed or incorrectly redacted. This saves time and improves reliability.

No, the Redact PDF tool is not available in the Adobe PDF Services API. Redaction is a feature that is only found in the desktop version of Adobe Acrobat Pro. You cannot automate redaction operations through the API for your web application or other automated workflows.
